Movement of the Lifter

1.

Outline

When the deck or the cassette is slid in, the cassette open/closed sensor turns on and, at the
same time, the pickup roller starts to move down, causing the light-blocking plate to leave the lifter
sensor, driving the cassette lifter motor and, ultimately, moving up the lifter.
The lifter keeps moving up until the lifter sensor detects the surface of paper. (In the case of the
deck right/left, a limiter is mounted to stop the lifter if it fails to stop moving up.)
When the deck or cassette open button is pushed, the drive gear of the lifter becomes free to let
the lifter move down on its own weight.
